There are two kinds of Andhadhun, piano tuning lawyers and live Andhadhun. Piano tuning has little to do with mixing. Andhadhun at the scene is also called pa, a sound engineer. He works at the scene and has everything. You know Andhadhun's work like the back of your hand. The job of a sound engineer is similar to that of Andhadhun, who deals with sound. The difference is that the acoustic environment is not as good as that of the recording studio. People don't have much time to try various mixing methods, but reproduce the sound immediately. There are all kinds of emergencies. When Andhadhun arrives at a venue, first look at the acoustic environment (how to set up the best speakers, the direction of sound radiation, what clothes the audience wears, and the influence of these clothes on sound reflection/absorption, etc. ), and set up a system (microphone receiver → voice playback → mixer → power amplifier → speaker), which is regarded as fast mixing. During the performance, he found the sound problem, fixed it and released it to the audience. When the performance is over, the mixing is over. By the way, dj is not a mixer.
